Hi guys, I need your help. I'm trying to sort the data by the variable "obs". This is how I tried to sort the data below.
The problem is, I have a variable name "obs"; this is.. a counter variable. something like _n_ in SAS. I do not know why it is not working. I even tried a similar example in UCLA webpage: http://www.ats.ucla.edu/stat/R/faq/sort.htm :it also does not seem to work. "*sort1.hsb2 <- hsb2[order(read) , ]"* Do you have any idea how to deal with this problem?? Thank you so much. -Hyo > colnames(ttx1) [1] "longitude 1" "longitude 2" "longitude 3" "longitude 4" "longitude 5" [6] "longitude 6" "longitude 7" "longitude 8" "longitude 9" "longitude 10" [11] "longitude 11" "longitude 12" "longitude 13" "longitude 14" "longitude 15" [16] "longitude 16" "longitude 17" "longitude 18" "longitude 19" "longitude 20" [21] "longitude 21" "longitude 22" "longitude 23" "longitude 24" "longitude 25" [26] "longitude 26" "longitude 27" "longitude 28" "longitude 29" "longitude 30" [31] "longitude 31" "longitude 32" "longitude 33" "longitude 34" "longitude 35" [36] "longitude 36" "longitude 37" "longitude 38" "longitude 39" "longitude 40" [41] "longitude 41" "longitude 42" "longitude 43" "longitude 44" "longitude 45" [46] "longitude 46" "longitude 47" "longitude 48" "longitude 49" "longitude 50" [51] "longitude 51" "longitude 52" "longitude 53" "longitude 54" "longitude 55" [56] "longitude 56" "longitude 57" "longitude 58" "longitude 59" "longitude 60" [61] "longitude 61" "longitude 62" "longitude 63" "longitude 64" "longitude 65" [66] "longitude 66" "longitude 67" "longitude 68" "longitude 69" "longitude 70" [71] "longitude 71" "longitude 72" "obs" > > sortedx1=ttx1[order(-obs),] Error in order(-obs) : object 'obs' not found [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
